Title: Medical appliance disposal container
Inventor: SIMPSON JAMES L
IPC: B01L1/00
Filed: 1990-01-24
Abstract: ABSTRACT OF THE DISCLOSURE    A  medical  waste  disposal  container  has  a  unitary  body structure formed of a substantially flat sheet having a plurality of laminated layers of compact fiberboard, and one or more thin pliable  layers  of  absorbtion  resistant plastic material.  The laminated sheet material contains a plurality of foldable sheet portions  that  are scored,  wrapped at  corners  and  adhesively joined together to define a bottom, sidewalls and a top of the body structure. The top has an opening, that is closeable by way of  a  flap  formed  in  the  sheet  material,  for  insertion  of discarded  medical  waste.  The  interior  of  the  container  is preferably  coated  with  an  absorption  resistant  material  to effectively provide a leakproof seal at the intersections of its sidewalls  and bottom.  Adhesion and additional  sealing of the foldable sheet portions is achieved in the course of manufacture by irradiating the laminate sheet material with infrared light, which causes the plastic layer that forms the outer wall surface of  the  sheet material  to  become  tacky,  so  that  it  becomes intimately bonded to an adjacent folded sheet portion to which it is joined, thus securing the wrapped sheet portions together.

IPC: B08B9/093
Filed: 1990-02-20
Abstract: A washer is described for cleaning the interiors of tanks that hold milk, beer, chemicals and so on.  A main body 2 reciprocates relative to a substantially surrounded and relatively fixed piston 19.  The body 2 oscillatably supports three nozzles 7 each of which is movable through an arc of 60° and which arc is angularly spaced from those corresponding to the other two nozzles 7 by further angles of 60°.  However, the body 2 and nozzles 7 are also indexed, during operation, in steps, around a further axis which is perpendicular to the axis of oscillation and which substantially corresponds to the longitudinal axis of the tank washer itself.  Thus, each nozzle 7 cleans not only on arc of 60° but rotates that arc through 360° so that the whole of the interior of a tank is both washed and substantially rinsed by the three nozzles 7.

Filed: 1990-11-14
Abstract: A flexural pivot is configured as a multi-piece device which is specifically configured to tolerate vibration and shock loading.  The flex pivot described uses pre-formed unitary (one-piece) support structures which have integral undercut areas, diametrically opposed slots for flexural member placement and key ways and the like, and near net shape geometry.  The flexural members are pre-brazed to facilitate the assembly process.  The design of the pre-formed support structures eliminates brazed joints which are common locations of fracture due to vibration and shock loading, resulting in a significantly strengthened pivot.  The overall configuration and method described provides an economical flex pivot, whereby the flex pivots are accessible for applications which have not heretofore been feasible.

Title: Feeding device for converters, free of harmonic distortion
Inventor: COURIER DE MERE HENRI E F M
IPC: H02M1/42
Filed: 1990-07-19
Abstract: ABSTRACT OF THE DISCLOSURE       The invention relates  to  an economic device  for feeding an electronic converter from the mains without the current  taken  from  the  mains  being  affected  by  an appreciable harmonic distortion,  whatever the nature of the load applied at the output of this converter.      This device comprises a buffer circuit formed by at least two capacitors 5a and 5b charged by the mains, in series, and discharged each in parallel across the input terminals 9a and 9b of the converter 10. As soon as the latter operates,  a fraction of the output HF energy is rectified by the bridge which adds its output signal to that delivered by the first bridge 3.  Thus, the supply voltage present at the terminals 9a and 9b has only a reduced ripple rate whereas the current taken from the mains  is  substantially  sinusoidal  in  phase  with  the voltage, whatever the nature of the load applied at the output, resistive, inductive, capacitive or non linear.      This  device  is  applicable  to most  electronic converters  used  as  ballasts,  transformers,  stabilised power supplies, etc..

Title: High pressure fluid regulator
IPC: G05D16/00
Filed: 1991-11-27
Abstract: ABSTRACT OF THE DISCLOSURE    A fluid pressure regulator provides features which enable an extended regulator life in high pressure service.  Dual flexible diaphragms provide chemical resistance in contact with the working fluid and abrasion and fatigue resistance in contact with a backup plate and piston assembly.  The backup plate has a bore which is sufficiently long and close fitting with the piston so that axial alignment is assured and there is minimal tendency for the piston to become cocked within the bore.  Provision is also made for preventing fretting corrosion between the piston and the backup plate by coating at least one of the surfaces, if necessary, to assure that dissimilar metals only are in contact in that couple.  Seals between the regulator housing body and the diaphragm and between the valve stem and diaphragm may be provided by resilient seal rings or by annular protrusions integrally formed on one or both of the diaphragms.
